Triolo was the Pirates’ competitive balance round pick in the 2019 draft.  He’s a solid all-around third baseman without any outstanding tool.  He was the best hitter for Houston in 2019, with a 332/420/512 line, including more walks (31) than strikeouts (30).  He improved steadily during his three years, with 271/360/372 and 344/434/457 lines as a freshman and sophomore, respectively.  Triolo has a good swing but only average bat speed, and hasn’t been able to pull the ball enough to produce a lot of over-the-fence power.  Scouts believe he has the potential for more power due to good strength.  He has average speed.  Sources were split on his defense at the time he was drafted, from average with an average arm to plus with an above-average arm.  As a pro, he’s shown that the more optimistic view was the accurate one.  Baseball America rated Triolo 115th in the draft class and MLB Pipeline 146th.  He signed for exactly the slot amount.

A-:  239/314/389, 234 AB, 19 2B, 5 3B, 2 HR, 27 BB, 49 K, 3-4 SB

Triolo had probably the best debut of the Pirates’ 2019 college position player draftees, although that’s a low bar.  His numbers were a bit better than they look; power is so depressed in the New York-Penn League that he finished tied for second in doubles and in the top 20 in slugging.  Triolo hammered LHPs for a .908 OPS, but had only a .651 figure against RHPs.  He started 17 games at short, in addition to being the team’s primary third baseman.  He looked at least passable there, although he’s probably not a shortstop going forward.


A+:  304/369/480, 421 AB, 29 2B, 15 HR, 42 BB, 94 K, 25-31 SB

Triolo spent the season at Greensboro and improved steadily all year.  His monthly OPS, starting in May, was:  .639 .824 .905 .958 .810.  His plate discipline was solid and some of the doubles started going over the fence.  He had only a minor platoon split and didn’t rely on the extreme home run environment at Greensboro.  He had seven home runs and a .752 OPS at home, eight and .915 on the road.  Defensively, he played at a major league level at third.  He also started five games at short.  Maybe most interesting of all, he did a great job stealing bases, although he isn’t a speedster.

Triolo had a very encouraging season and is probably one of the more overlooked prospects in the system.  At 23, he was a little old for the level, so AA will be an important test.  Hopefully he can make it to AAA in 2022.
