WTM’S PIRATE PLAYER PROFILES

Mathisen played all over the field in high school, including shortstop and pitcher, but is expected to be a catcher as a pro.  He obviously has very good athleticism, but may have fallen a little in the draft because he hadn’t caught that much.  Baseball America rated him the top prep catcher and the 47th best draft prospect.  Still, scouts believe he has the ability to be a good defensive catcher with a strong arm.  He has good strength and should be able to hit for both power and average.  He also has average speed, which would be above average for a catcher.  He had a commitment to Texas, but was eager to start his pro career and signed right after the draft for the slot amount.

2012
R:  295/388/374, 139 AB, 8 2B, 1 HR, 16 BB, 19 K, 10-18 SB

Mathisen had a good debut in the GCL.  He hit for average and showed very good plate discipline.  The power hasn’t shown up yet, but that’s not unusual for an 18-year-old.  He split catching duties with Jin-De Jhang and did well behind the plate, throwing out 36% of would-be base stealers.  He was out briefly with a foot fracture and after returning often came out of games he was catching in the late innings, but he still ended up getting significant time behind the plate.  Baseball America named him the 5th best prospect in the GCL in a strong year for the league.

2013
R:  409/552/455, 22 AB, 1 2B, 7 BB, 2 K
A-:  269/394/269, 26 AB, 5 BB, 7 K, 1-1 SB
A:  185/256/210, 119 AB, 3 2B, 9 BB, 22 K, 1-1 SB

Mathisen had a rough year in 2013.  The Pirates pushed him to West Virginia, which was an ambitious assignment both due to his age (he played the season at 19) and his inexperience at such a tough position.  He had problems on both offense and defense.  Behind the plate, his inexperience in receiving showed, although he did throw out a decent 26% of base stealers.  At the plate, he struggled to hit with any authority, showing no power.  The one positive sign was that his K rate wasn’t too bad, so he wasn’t completely overwhelmed.  In late May, he was shut down due to shoulder problems and he ended up having labrum surgery.  The shoulder apparently had been bothering him for much of the season, so it may account for some of his struggles.  He returned in time to rehab in the GCL and at Jamestown.

2014
A:  280/344/360, 375 AB, 17 2B, 2 3B, 3 HR, 33 BB, 54 K, 6-8 SB

Mathisen’s 2013 season wasn’t encouraging, but it’s impossible to know how much resulted from inexperience and from the shoulder injury.  The Pirates figured to have three catching prospects who were ready for the low A level in 2014:  Mathisen, Jhang and 2013 first rounder Reese McGuire.  The team initially addressed the situation by indicating that it would move Jhang up to Bradenton.  Partway through spring training, though, the Pirates also announced that Mathisen would move to third base in 2014.  He spent the season as the regular there with West Virginia, except for missing a month starting in late June with a leg injury he sustained in a collision at third.  He made solid progress at the plate.  After getting only one extra base hit in April, he had a minor power binge in May, including all three of his HRs.  He posted an .807 OPS in June, then after missing most of July put up a .720 OPS in August.  Overall he did a good job of controlling the strike zone.  He had a huge platoon split, with a .922 OPS against LHPs and .633 against RHPs.  Mathisen had trouble with errors at third, with just a .910 fielding percentage, but that’s not surprising considering the position switch.

After the progress he made in 2014, Mathisen would be looking very good as a catching prospect, but the position switch definitely puts more pressure on his bat.  The biggest question will be whether he can add power, as he’s shown an ability to hit for average and get on base.  He should be the starter at third for Bradenton in 2015 and will play the season at age 21, which is a good age for high A.
