Heaney was dealing with left calf cramping when he exited Saturday's game against the Phillies, Noah Hiles of the Pittsburgh Post-Gazette reports.

EDGE Analysis

Heaney delivered six strong innings, allowing one earned run on four hits and no walks before being pulled. He threw an errant pitch against Nick Castellanos and was lifted immediately afterward, creating some concern of an arm injury that proved to be unfounded.

Heaney exited Saturday's start against the Phillies with a trainer, Alex Stumpf of MLB.com reports.

EDGE Analysis

Heaney completed six innings while allowing only one earned run on four hits and no walks before being pulled. The exact nature of the injury is unclear, but he threw an errant fastball to Nick Castellanos immediately before being pulled in the middle of the at-bat.

Heaney allowed two runs on five hits and struck out three without walking a batter over 5.2 innings in a no-decision Sunday versus the Padres.

EDGE Analysis

Heaney rebounded well from his previous outing, in which he allowed five runs over five innings against Arizona. He came up an out short of a quality start Sunday, and he also missed out on the win after Tanner Rainey and Caleb Ferguson combined to squander the Pirates' lead in the seventh inning. Heaney is now at a 3.39 ERA, 1.19 WHIP and 47:24 K:BB across 66.1 innings over 12 starts this season. He's allowed two runs or fewer in four of his last five starts and in eight of his 12 outings this year. He is projected to make his next start at home versus the Phillies.

Heaney (3-4) allowed five runs on eight hits and three walks while striking out two over five innings to take the loss Monday versus the Diamondbacks.

EDGE Analysis

After allowing a total of four runs over 16 innings across his last three starts, Heaney took a significant step back in this outing. He gave up a pair of home runs, which accounts for the last three runs on his line in one of his worst starts of the season. The southpaw has also walked at least three batters in five of his last six appearances. He's at a 3.41 ERA, 1.22 WHIP and 44:24 K:BB over 60.2 innings across 11 starts this season. Heaney's next outing is projected to be at San Diego.

Heaney (3-3) picked up the win in Wednesday's 3-1 victory over the Reds, allowing one run on three hits and two walks over five innings. He struck out four.

EDGE Analysis

The veteran southpaw tossed 64 of 97 pitches for strikes as he gave up two runs or fewer for the third straight start, and the seventh time in 10 trips to the mound this season. Heaney's been far from dominant -- he managed only nine swinging strikes Wednesday, and he sports a 14:9 K:BB in 19.2 innings over four starts in May -- but he continues to avoid hard contact, and all three hits he gave up to the Reds were singles. He'll take a 2.91 ERA and 1.13 WHIP into his next outing, which is scheduled to come on the road early next week in Arizona.

Heaney didn't factor into the decision in Friday's 8-4 loss to the Phillies after giving up one earned run on four hits and three walks while striking out two batters in five innings.

EDGE Analysis

Heaney was on his way to taking home the win before the Pirates' bullpen gave up the lead in the seventh inning. The 33-year-old southpaw still dropped his ERA to 3.02 with his performance and will now look to pick up his first win since April 23 when he faces the Reds at home next week.

Heaney didn't factor into the decision in Saturday's 3-2 extra-innings loss to Atlanta, giving up two runs on four hits and three walks over six innings. He struck out two.

EDGE Analysis

The veteran southpaw only managed four swinging strikes on the afternoon among his 82 pitches, and all four of the hits off him went for extra bases including a Matt Olson solo shot in the third inning, but Heaney still managed to deliver his fourth quality start of the season. He'll take a 3.15 ERA, 1.12 WHIP and 36:16 K:BB through 45.2 innings into his next outing, which is scheduled to come on the road next weekend in Philadelphia.

Heaney (2-3) took the loss Sunday against San Diego, allowing four runs on eight hits and four walks over 3.2 innings. He struck out three.

EDGE Analysis

After pitching to a 1.72 ERA in his first five starts this season, Heaney's now given up eight runs in just 8.1 innings over his last two outings. The left-hander's ERA is consequently up to 3.18 with a 1.11 WHIP and 34:13 K:BB across 39.2 innings this year. Heaney will look to get back on track in his next start, currently scheduled for next week against Atlanta.

Heaney (2-2) allowed four runs on five hits and three walks over 4.2 innings while taking a loss against the Cubs on Tuesday. He did not record a strikeout.

EDGE Analysis

Heaney worked through three scoreless frames before things turned south. Carson Kelly knocked a two-run shot in the fourth inning, and Pete Crow-Armstrong hit a two-run homer in the fifth. Heaney had given up just one home run through 31.1 innings entering Tuesday's outing. His shortest start of the season bumped his ERA up to 2.50 with a 31:9 K:BB through 36 innings. Heaney is lined up to face the Padres at home this weekend.

Heaney (2-1) earned the win Wednesday against the Angels, allowing one hit and zero walks while striking out nine batters across six shutout innings.

EDGE Analysis

Heaney's bid for a no-hitter was broken up by a Travis d'Arnaud double in the fifth inning, but the southpaw managed to close out the inning without allowing a run to score. Wednesday's performance gives Heaney 13.1 consecutive shutout frames and a 13:2 K:BB across his last two starts. He's due for a test during his next outing, however, which is tentatively scheduled to come at home against the Cubs, who boast the highest OPS (.806) of any team in the majors.
