The Seattle Mariners have called up right-handed pitcher Max Povse from Double-A Arkansas and have optioned fellow right-hander Rob Whalen to Double-A. Additionally, the Mariners designated left-hander Dillon Overton for assignment, according to MLB Roster Moves.
The 23-year-old Povse has pitched in nine games for Double-A Arkansas this season, starting eight. He has gone 3-2 with a 3.46 ERA, allowing 34 hits while striking out 32 batters over 39 innings of work.
Seattle acquired Povse (as well as Whalen) in a trade with the Atlanta Braves back in November.
Povse, who played his college baseball at the University of North Carolina at Greensboro, was originally selected by the Los Angeles Dodgers in the 42nd round of the 2011 MLB June Amateur Draft. However, he failed to sign and was drafted by the Braves in the third round three years later.
Povse is yet to pitch in a game at the major-league level.
Whalen has appeared in two games with the Mariners this season, starting one. Over 7.1 frames of action, the 23-year-old has surrendered five runs on seven hits.
Overton pitched in nine games with Seattle this year, making one start. He registered a 6.38 ERA across 18.1 innings, giving up 21 hits and four home runs while only fanning eight hitters.
The 25-year-old also struggled mightily at Triple-A Tacoma, pitching to the tune of a 9.33 ERA over 27 frames.
The Mariners are currently 33-37 and sit a whopping 13.5 games behind the Houston Astros for first place in the American League West Division.
They will wrap up a three-game series with the Texas Rangers on Sunday.
