Andriese (0-2) got the loss Tuesday, allowing five runs on five hits while striking out four over two innings against the Cubs. Andriese was hit hard, allowing two home runs and two doubles in the brief outing. The 29-year-old was filling in the rotation spot of the injured Clay Buchholz (elbow), but it's unclear if he'll keep that spot the remainder of the season or slide back into a bullpen role. Since joining Arizona, the 29-year-old has a bloated 9.00 ERA and 1.78 WHIP over 13 appearances (one start).
Andriese will start Tuesday against the Cubs. Andriese will enter the rotation in place of Clay Buchholz, who was ruled out for the remainder of the season after suffering an elbow injury. The right-hander has made four starts this season, but he's been working in relief since joining the Diamondbacks at the end of July, so he likely won't throw more than a few innings in Tuesday's spot start. It's unclear if Andriese will stick in the rotation after Tuesday or if he'll return to the bullpen, though that could depend on how he fares. He owns a 4.76 ERA, 1.32 WHIP and 59:18 K:BB across 59.2 big-league innings this season.
Andriese was torched for seven runs on eight hits and two walks over 1.1 innings of relief in Monday's 13-2 loss to the Rockies. The seven earned runs were one more than Andriese had allowed in his last 12 appearances combined and resulted in his season ERA jumping from 3.99 to 4.76. The right-hander is likely to serve as an innings eater out of the bullpen for the remainder of the season, but don't expect him to see much duty in high-leverage spots even while the Diamondbacks' late-inning situation remains unsettled for the moment.
Andriese was recalled from High-A Visalia on Tuesday. Andriese is back with the Diamondbacks after making one appearance for the Rawhide, striking out five across 3.2 innings. There had been talk of stretching Andriese out to start, but he threw only 62 pitches in that aforementioned outing, so he may be limited to a long-relief role down the stretch. Andriese has a 4.09 ERA and 73:21 K:BB across 72.2 big-league innings this season.
Andriese, who was optioned to High-A Visalia on Tuesday, will be stretched out as a starter while he remains in the minors, Martin Oppegaard of MLB.com reports. The rotation has been a strength for the Diamondbacks this season, but the team doesn't have much in the way of depth behind its current five starters with Taijuan Walker (elbow) out for the season and Shelby Miller (elbow) facing a hazy timeline to return from the disabled list. With that in mind, Andriese, who made 38 starts with the Rays across the last two seasons before transitioning to the bullpen in 2018, will at least provide some decent insurance if Arizona loses another rotation member to an injury. Since Andriese hasn't tossed more than 58 pitches in any of his appearances, he'll likely require at least two outings in the minors before he's ready to handle a starter's workload. If the Diamondbacks' top five rotation options all remain healthy by the time he's ready to return to the big leagues, however, Andriese would presumably reprise a bullpen role.
