The A’s Montas is showing positive signs, making his next scheduled start.

OAKLAND — Things are going in the right direction for A’s starter Frankie Montas, who reported no problems a day after returning to the mound after dealing with shoulder inflammation.

Montas was experiencing “post-pitching soreness,” A’s manager Mark Kotse told reporters before Friday night’s series opener against Texas. Kotse said his right-hander, a hot trade commodity, is “good to go” for his next start before the Aug. 2 deadline.

However, the A’s have yet to list a starting pitcher for any game in the three-game series that begins Monday against Houston at home.

Pitching for the first time since leaving his July 3 start after just one inning due to a shoulder problem, Montas pitched three innings against the Detroit Tigers on Thursday. He was pulled after throwing 53 pitches and striking out five batters. Montas’ fastball floated 96-97 mph to start Thursday’s game and hovered around 94 mph.

He received a no decision in Oakland’s 5-0 win in the second game of the doubleheader.

Scouts from around the league were on hand Thursday to see how the 29-year-old Montas would fare in his return. As one of the more appealing starting pitchers available on the market, the expectation is that Montas will be dealt.
