33 Tyson Ross RP

The Cardinals aren't listing Ross as a probable starter for any of their next four games, suggesting he has been returned to a bullpen role.

When Ross was first acquired and added to the active roster Aug. 7, the Cardinals indicated that he would likely be ticketed for long relief. The right-hander didn't make any appearances out of the bullpen, however, before entering the rotation Aug. 12 in Kansas City when Luke Weaver (finger) was a late scratch. Though Ross fared well in the outing with six innings of two-run ball, Weaver is listed as the probable starter for Friday's game against the Brewers, so it appears Ross's performance wasn't quite enough to garner him another turn in the rotation just yet. St. Louis could entertain moving Ross back into the rotation if young starters like Weaver, Austin Gomber and John Gant struggle in their subsequent outings.

Ross (7-9) threw six innings Sunday, allowing two runs on four hits and two walks in the 8-2 win over the Royals. He struck out four and earned the victory.

Ross was solid in his first appearance with St. Louis, stepping in for a spot start after Luke Weaver (finger) was a late scratch. Unless Weaver goes to the disabled list, Ross likely will find himself in more of a bullpen role rather than starting. He dropped his ERA to 4.38 with 111 strikeouts in 129.1 innings overall on the season.

Ross will start Sunday's game at Kansas City, Jenifer Langosch of MLB.com reports.

Scheduled starter Luke Weaver was a late scratch due to a cut on his finger, so Ross will make his first appearance since being acquired by the Cardinals last week. The veteran right-hander had a 4.45 ERA, 1.33 WHIP and 107:52 K:BB in 22 starts with the Padres this year.

Ross was added to the Cardinals' active roster ahead of Tuesday's game against the Marlins.

Ross, who was claimed off waivers from the Padres over the weekend, will take the roster spot of John Brebbia, who was optioned to Triple-A Memphis in a corresponding move. The veteran right-hander will start out in the Cardinals' bullpen, though he'll remain an option to start should an opportunity arise. Ross owns a 4.45 ERA through 123.1 innings (22 starts) this season.

Ross will begin his time with the Cardinals in the bullpen, Joe Trezza of MLB.com reports.

It was initially assumed that the Cardinals acquired Ross in order for him to be used in the rotation, but it appears that he'll be a reliever for now. The decision likely means Austin Gomber will remain a rotation member for at least one more start. Ross's mediocre 4.45 ERA looks worse when factoring in pitcher-friendly Petco Park, giving him an 89 ERA+, though it's possible his stuff will play up in relief.
