Isaac Mattson - MLB News, Rumors, & Updates

Sent to Indianapolis The Pirates optioned Mattson to Triple-A Indianapolis on Tuesday, Jason Mackey of MLB.com reports.

Back in big leagues The Pirates recalled Mattson from Triple-A Indianapolis on Saturday, Colin Beazley of the Pittsburgh Post-Gazette reports.

Impact Mattson has given up four runs across his last two big-league appearances, but the Pirates will bring him back into their bullpen as the replacement for Antwone Kelly. Sporting a 4.93 ERA and 1.56 WHIP through 34.2 innings in the majors, Mattson will likely be limited to low-leverage work.

Demoted to Indianapolis The Pirates optioned Mattson to Triple-A Indianapolis on Wednesday, Kevin Gorman of TribLive.com reports.

Impact Mattson (1.2 innings, 39 pitches) and Brandon Eisert (2.1 innings, 41 pitches) both saw heavy usage out of the bullpen in Tuesday's 8-7 loss to Arizona in 12 innings, so Pittsburgh will call up a pair of fresh relief arms from Triple-A (Noah Murdock and Hunter Barco) to replace them ahead of Wednesday's series finale. During his six-plus-week stay in the majors, Mattson appeared in 13 games and turned in a 6.39 ERA, 1.74 WHIP and 15:4 K:BB across 12.2 innings.

Pitches scoreless inning in loss Mattson allowed two hits while striking out two in one inning on Monday in a 5-0 loss to the Padres.

Impact Mattson was a revelation out of the bullpen for the Pirates last season posting a 2.45 ERA in 44 appearances after only making seven appearances before being called up in May. The right-hander has had a heavy workload so far pitching in six out of Pittsburgh's 10 games posting a 3.00 ERA and seven strikeouts. The Pirates bullpen does not have many proven right-handers other than Dennis Santana, which means Mattson could continue appearing in many games this season.
