The Toronto Blue Jays will turn to right-hander Kevin Gausman in an attempt to escape an early-season funk when they meet the Arizona Diamondbacks in the finale of a three-game set in Phoenix on Sunday afternoon.

The Diamondbacks secured the series win with a 6-2 victory Saturday on Corbin Carroll’s grand slam that broke a tie in the eighth, keeping each team on its current path.

Arizona has won four games in a row and 10 of its past 13, and has not lost a series since being swept by the Los Angeles Dodgers to open the season.

Carroll’s homer secured the Diamondbacks’ 10th comeback win of the season.

“We’ve played a lot of (close games),” Carroll said. “Maybe when you are in those situations, you know you don’t have to press.”

The Blue Jays have lost four straight games, six of their past seven, and have not won a series since a season-opening sweep of the Athletics.

Toronto has played through injured-list stints to George Springer, Alejandro Kirk and Addison Barger this year.

Gausman (0-1, 2.42 ERA) will oppose Arizona right-hander Ryne Nelson (1-1, 3.54) on Sunday.

Gausman has given up three runs or fewer in each of his four starts this season but remains winless despite his low ERA. In two of Gauman’s starts, the Blue Jays have managed just one run.

“We’re not scoring, but we’re definitely not scoring when he’s out there,” Toronto manager John Schneider said. “I feel like he’s been as steady as he has ever been here. So looking for him to continue do that.

“He’s in a good place. Physically his delivery is sound. That’s the only time Kevin has been in trouble, with his delivery, and that’s been really good.”

Gausman gave up one run and three hits, striking out 21, over his first two starts, both no-decisions. He gave up three runs and six hits in his last outing, when he went five innings of a no-decision in the Blue Jays’ 9-7, 10-inning victory at Milwaukee on Tuesday.

Gausman has been successful against the Diamondbacks, going 6-2 with a 3.23 ERA in 10 career appearances (nine starts).

Nelson, meanwhile, has been betrayed by his defense at times. He has given up 14 runs in four starts, but only eight runs were earned. Atlanta scored five unearned runs off him in his second start, a 17-2 loss on April 2.

Nelson gave up two runs (one earned) over 5 1/3 innings in his most recent outing, a no-decision in a 9-7 loss at Baltimore on Monday, when the bullpen could not hold a 7-1 lead.

Nelson has increased his slider and curveball usage this season to complement his high-90s fastball. Against the Orioles, he had seven strikeouts — three on a fastball, three on a slider, and one on a curve.

“He’s had success pitching with velo (velocity) and only velo, but we want to allow him to go out there and change speeds, side-to-side as well as up-and-down,” Arizona manager Torey Lovullo said. “It’s a very conscious effort to have him pitch a little bit more than just going out there and let it eat with straight veto for 100 pitches.”

Nelson is 1-0 with a 2.45 ERA in three career outings (all starts) against the Blue Jays.
