Joe Musgrove

Musgrove's 3.82 FIP in 2019 indicated that he deserved better than his 4.44 ERA. As it turns out, that number was a near-perfect estimation of his ERA in 2020, which came in at 3.86 in eight starts, a number cut short by a spell on the injured list due to triceps inflammation. For the fourth consecutive year, Musgrove's FIP beat his ERA, coming in at a career-low 3.42. His underlying numbers looked like they belonged to an entirely different pitcher than who he was in his first four seasons. His K% sat in a very narrow band between 20.6% and 21.9% in those years before shooting up to 33.1% in 2020. That did come with some control problems, as he posted a 9.6 BB%, well above his previous career high of 6.3%, though he also produced a career-high 48.4% groundball rate. The good here definitely outweighs the bad, and while the sample was quite small, Musgrove looks more interesting than ever heading into 2021.

Musgrove's baseline skills look better than a pitcher who ended up with a 4.44 ERA. Last season marked the second consecutive year where Musgrove's FIP was at least half a run lower than his ERA, as he and the Pirates struggled to strand baserunners. He allowed four or more earned runs in nine of his 31 outings, and had a 7.17 ERA the third time through a lineup. His slider took a big step forward in 2019 in terms of pitch value, but it did not have a sufficient supporting cast despite his fastball spin rate being in the 80th percentile league-wide. Last season was the first with a significant workload for Musgrove, but the overall results did not look much different from previous efforts. This feels like yet another example of the team's strategy holding back a talented arm, so perhaps the change in pitching coach may lead to a different path forward for Musgrove. The skills are there for better results.

Musgrove was limited by injuries but performed at a high level between DL stints, creating some excitement heading into 2019. After turning the page on a shoulder issue, Musgrove made his Pirates debut May 20 and blanked the Cardinals over seven innings. A finger infection sidelined Musgrove again in July, but he returned to post an even 1.0 BB/9 in 62.1 innings after the break, lowering his walk rate to just 4.7% for the season. His 20.6 K% was underwhelming, though an 11.4% swinging-strike rate and an excellent 68.3% first-pitch-strike rate hint at room for growth in that department. The Pirates were forced to shut Musgrove down early and sent him for surgery to repair his right abdominal wall and to heal a stress reaction in his pelvic bone, but he was expected to have a relatively normal offseason. There's no doubt that Musgrove will have a rotation spot when healthy. The command is there for him to take his performance to the next level.

For some, it is a tale of two halves. For Musgrove, it was a tale of two roles. As a starter, Musgrove posted a 6.12 ERA with a 1.51 WHIP. After being demoted to the bullpen, he registered a sparkling 1.44 ERA with a stingy 0.86 WHIP. Sometimes, this is just happenstance, with regression occurring after the role change, not because of it. However, in this instance, Musgrove increased the use of his fastball (adding three mph), slider and cutter while barely throwing his sinker and curveball. The results were astounding, as Musgrove's swinging-strike rate gained three percentage points, while his walks and homers dropped significantly. Focusing on homers, as a starter, Musgrove surrendered 16 in just 78 innings compared to only two in 31.1 frames out of the bullpen. Just when it seemed he was poised to become one of the useful non-closer fantasy relievers in the Chris Devenski or Chad Green mold, Musgrove was dealt to the Pirates as part of the Gerrit Cole trade. He will return to starting in Pittsburgh, and more growing pains should be expected.

Musgrove excelled at the upper levels of the minor leagues in 2016, earning a look in the Astros' rotation over the final two months. Aside from one eight-run blowup at Baltimore, Musgrove was mostly impressive as he was able to maintain a good walk rate against more advance hitters while continuing to miss bats at a strong clip. His 4.23 FIP suggests he may have overachieved slightly in the ratio categories, but command and control give Musgrove a nice floor as he enters his age-24 season and continues along the major-league learning curve. The Astros' signing of Charlie Morton and a potential role change for Chris Devenski cloud Musgrove's status somewhat, but there are health concerns at the top of the rotation, and Musgrove should serve as the top fill-in if he misses out on a rotation spot out of camp. He's more than an AL-only consideration.

Musgrove, Toronto's first pick in the compensation round of the 2011 draft (46th overall), was acquired by the Astros in 2012 and has spent the past four years in the lower levels of their minor league system. His stock has finally started to rise, however, as he opened 2015 with Low-A Quad Cities and finished the year at Double-A Corpus Christi. Between three levels last season, he appeared In 19 games (14 starts) and went 12-1 with a 1.88 ERA, 0.92 WHIP and 99:8 K:BB ratio over 100.2 innings. The 23-year-old right-hander sports a mid-to-low 90s fastball, plus slider and plus-plus command, but his future as a big league starter or reliever is unclear. He's likely to return to Corpus Christi or open 2016 with Triple-A Fresno.
