Locke came to the Pirates with RHP Charlie Morton and CF Gorkys Hernandez in a hugely unpopular trade for the hugely overrated (by Pirate fans) Nate McLouth.  Baseball America ranked Locke as the 7th best prospect in the Braves’ system going into 2009, despite a so-so 2008 season.  BA also rated him the 14th best prospect in the South Atlantic League for 2008.  Locke’s fastball sits around 88-92 and can reach a little higher.  He throws a changeup that’s generally been very effective and a curve that’s been less so.  He’s generally kept the ball in the park and has been more effective against RH than LH hitters.

R:  4-3-0, 4.22 ERA, 1.34 WHIP, 32 IP, 1.4 BB/9, 10.7 K/9

Had a solid debut in rookie ball.  Opponents hit .299 against him, but his walk and K rates were excellent.

R+:  7-1-1, 2.66 ERA, 0.92 WHIP, 61 IP, 1.2 BB/9 ,10.9 K/9 

In the advanced rookie Appalachian League, Locke was much harder to hit and his walk and K rates were even better.

A:  5-12-0, 4.06 ERA, 1.35 WHIP, 139.2 IP, 2.4 BB/9, 7.2 K/9

Locke wasn’t as dominant in full season ball, but he didn’t walk many and allowed only six HRs.

A+ (Atl):  1-4-0, 5.52 ERA, 1.60 WHIP, 45.2 IP, 5.1 BB/9, 8.5 K/9
A+ (Pgh):  4-4-0, 4.08 ERA, 1.42 WHIP, 81.2 IP, 2.0 BB.9, 6.2 K/9 

Before the trade, Locke struggled with his mechanics, leading to control problems for the first time in his career.  After the trade, the struggles continued, as he had an ERA of 5.31 in June and July.  He started turning things around in his last July start and had an ERA of 2.58 from that point on.  The strong stretch began after one meltdown in which he failed to get out of first inning.  His walk rate dropped dramatically with Lynchburg as the Pirates got him to focus more on throwing strikes.  His K rate also dropped significantly, but was increasing again late in the year.

A+:  9-3-0, 3.54 ERA, 1.11 WHIP, 86.1 IP, 1.5 BB/9, 8.7 K/9
AA:  3-2-0, 3.59 ERA, 1.20 WHIP, 57.2 IP, 1.9 BB/9, 8.7 K/9

Went back to high A and turned things around.  His walk and strikeout numbers were excellent, and his pitching overall was better than his ERA indicates.  He moved up to Altoona in mid-July and put up nearly identical numbers there.  He had two bad starts out of ten and pitched very well in all the others.

AA:  7-8-0, 4.03 ERA, 1.31 WHIP, 125 IP, 3.3 BB/9, 8.2 K/9
AAA:  1-2-0, 2.22 ERA, 1.20 WHIP, 28.1 IP, 2.9 BB/9, 7.9 K/9
MLB:  0-3-0, 6.48 ERA, 1.86 WHIP, 16.2 IP, 5.4 BB/9, 2.7 K/9 

The Pirates sent Locke to Altoona to start the season, partly due to their desire to have some veterans in the AAA rotation as insurance.  He’d been added to the 40-man roster in the off-season.  He struggled early, as his stuff seemed flat and his velocity was down in the mid- to upper-80s.  May was an especially bad month, as he had a 7.01 ERA and walked 16 in 25.2 IP.  He pitched much better after that, though, and moved up to Indianapolis in August.  He started five games there and pitched very well in most of them.  The Pirates brought him in September and added him to the rotation for four starts.  He struggled with his control and mostly pitched poorly, which is hardly surprising.  He may have been tiring, as his velocity declined in each start.

AAA:  10-5-0, 2.48 ERA, 1.19 WHIP, 141.2 IP, 2.7 BB/9, 8.3 K/9
MLB:  1-3-0, 5.50 ERA, 1.37 WHIP, 34.1 IP, 2.9 BB/9, 8.9 K/9

Locke returned to AAA and had an outstanding season.  He improved throughout the season; after the AAA All-Star break, he had a 1.57 ERA and allowed just a .212 opponents’ average.  He had a significant platoon split on the season.  Left-handed batters hit only .197 against him with no HRs, while right-handers hit .257 with nine HRs.  Baseball America named him the International League’s 9th best prospect, although it was an extraordinarily weak season for that league, prospect-wise.  The Pirates brought Locke up in August for two relief appearances, then brought him back in September.  He spent the month in the rotation, making six starts.  He struggled in half and pitched well in the other half.  One very encouraging sign is that he had excellent walk and strikeout rates, and he didn’t get hammered; opponents hit 267/327/422 against him.  He tended to pitch well for several innings and then give up a big HR to somebody; he allowed six, better than one every six innings.  He did a far better job of throwing strikes than in his 2011 callup.  His fastball velocity was higher than it’s been at times, averaging over 90 mph in four of his six starts and 90.8 overall.  Both FIP and xFIP suggest he pitched better than his ERA, although it’s a small sample size.  Locke is not a groundball pitcher, so the longball could be a continuing problem for him.

MLB:  10-7-0, 3.52 ERA, 1.38 WHIP, 166.1 IP, 4.5 BB/9, 6.8 K/9

With Francisco Liriano and Jeff Karstens starting the 2013 season on the disabled list, Locke competed with Kyle McPherson, Jonathan Sanchez and Jeanmar Gomez for the last two rotation spots.  He ended up getting one spot more by default than anything, because he didn’t have a great spring.  He proceeded to have a remarkable first half, going 9-2, 2.11 in his first 19 starts and making the All-Star team.  His success came despite peripheral numbers that weren’t nearly as impressive as his ERA.  At that point, he’d walked 51 and fanned 79, and had a batting average on balls in play of .231.  Apart from the final numbers, Locke raised concerns due to his habit of falling behind in the count on a regular basis.  In fact, he led the NL in walks for the year.  Locke’s first half triggered considerable disagreement between statheads, who said he was due for regression, and other fans who bristled at the idea.  Unfortunately, the statheads proved to be right.  Locke’s BABIP skyrocketed to .374 and his WHIP to 1.87.  As a result, he went 1-5, 6.66 in his last eleven starts.  The Pirates removed him from the rotation temporarily in September, hoping some time off would help him get back on track, but it didn’t work.  Locke was left off the playoff roster.

On the positive side, Locke had a 53.2% groundball rate and allowed only 11 HRs.  His velocity stayed consistent all year, with his fastball averaging a little over 90.  This gives reason to hope he’s not the second coming of James McDonald, who had a great first half in 2012 only to fall apart, so far permanently, in the second half.  Unlike Locke, McDonald lost velocity, as well as the sharpness of his curve, and Locke hasn’t had any arm problems, as McDonald did.  Locke’s final numbers probably ended up somewhere near his real ability level, so it’s realistic to think he can be effective in the future as a 4th or 5th starter.  His xFIP (4.19) wasn’t a great deal higher than his ERA.

Locke went into spring training expected to compete for a starting job, but with Edinson Volquez signed for a guaranteed $5M, Wandy Rodriguez healthy, and Locke still having an option, the odds were against him.  As it was, he ended up missing much of the spring with an oblique injury and opened the season on the disabled list.  Once he’s healthy, he figures to head to Indianapolis, but he’ll almost certainly appear in Pittsburgh at some point.
