The Diamondbacks have signed right-hander Erich Uelmen to a minor league deal, according to his transactions tracker at MLB.com. He’s been assigned to the Complex League for now but will presumably report to a higher affiliate after getting some work in.
Uelmen, now 28, was drafted by the Cubs and was a starter on his way up the minor league ladder. He didn’t have much success in that role as he reached the higher levels, so the Cubs moved him to the bullpen at Triple-A. The initial results were encouraging, as Uelmen finished 2022 with an earned run average of 2.79 in 42 innings at the top minor league level. His 12.8% walk rate was on the high side but he punched out 29.1% of batters faced and also got grounders on 55.3% of balls in play.
The Cubs also gave Uelmen his major league debut that year, as he pitched 27 innings for them that year. He had a passable 4.67 ERA in that time with a subpar 17.2% strikeout rate, average-ish 9.8% walk rate and decent 47.6% ground ball rate.
Late in 2022, the Cubs re-signed Drew Smyly and bumped Uelmen off the roster. He was then traded to the Phillies for cash but had a challenging season with his new club. He only tossed one inning in the majors and just 17 2/3 in the minors, spending a significant amount of time on the IL. He had a 4.08 ERA in that limited minor league action before getting recalled in late September and placed on the major league 60-day IL with a right flexor strain when the Phils needed to open a roster spot.
Uelmen was outrighted by the Phils at the end of the season and remained unsigned until signing with the Snakes. He’ll presumably undergo something of a delayed Spring Training for a little while before moving into a depth position for the Diamondbacks. The relief corps in Arizona hasn’t been strong this year, with a collective 4.38 ERA that comes in 23rd out of the 30 clubs. If Uelmen can earn a roster spot, he has two option years remaining and has less than a year of service time.
Most likely he’s to start for their Triple-A club and not much else. Most of their starters are either injured or in the MLB rotation. Cristian Mena and Yilber Diaz being the most notable pitching prospects on that team and Mena could be MLB-bound if they don’t get decent production out of Ryne Nelson or Tommy Henry over the next month.
I sure hope they don’t call up Mena yet. He’s not exactly killing it in Reno. Pretty much the opposite.
