Heaney, who was placed on the 15-day disabled list Wednesday with a left flexor muscle strain, hopes to get better with rest, as his UCL has been deemed healthy by team doctors, MLB.com's Alden Gonzalez reports.

EDGE Analysis

It's easy to jump to conclusions with an injury like this and assume the worst, but the general sense among people that cover the team is that Heaney has a chance to get back on the mound without going under the knife. The Angels will likely be pretty careful with him, so he should be out longer than the 15-day minimum, but it's not yet time to cut bait with Heaney in deeper formats. Nick Tropeano is expected to come up from Triple-A and take the open rotation spot, but Tyler Skaggs should also be ready to join the rotation later this month, so Tropeano's stay in the rotation could be brief.

Heaney was placed on the 15-day disabled list Wednesday with a left flexor muscle strain, Jeff Fletcher of the Orange County Register reports.

EDGE Analysis

According to Fletcher, Heaney had a noticeable dip in his velocity during Tuesday's start against the Cubs, which resulted in a loss. A flexor muscle strain is a concerning injury for pitchers as forearm injuries can often lead to more significant problems down the line. He'll be shut down for the time being, and the Angels figure to release a timetable for his return in the near future. The Angels have yet to make a corresponding move to replace Heaney on the active roster.

Heaney (0-1) took the loss Tuesday against the Cubs as he allowed four runs on seven hits over six innings. He struck out seven and didn't walk a batter.

EDGE Analysis

Other than a rough third inning, Heaney was brilliant, but the Cubs give little room for error. Matt Szczur and Anthony Rizzo mashed home runs off Heaney to account for three of the four Chicago runs. Heaney induced 13 swinging strikes and was nasty at times. Heaney posted a 3.49 ERA last season in 18 starts.

Heaney (illness) allowed two hits, walked one, and struck out one in two scoreless frames Thursday.

EDGE Analysis

Heaney skipped a start due to an illness, but appears to be better now. After the start, the left-hander came out and said "I have energy. I am not dying. It's great." This is a good development, as he can now get back to his spot at the back of the Angels rotation.

Heaney will not start Saturday due to an illness, Jeff Fletcher of the Orange County Register reports.

EDGE Analysis

Heaney was expected to make his spring debut in the contest against the Mariners. Heaney has been suffering from the ailment for at least a week, but there has been no indication that he will need to miss extended time, as he is expected to start Wednesday.

Heaney is believed to be the Angels' No. 4 starter to begin the season, the Orange County Register reports.

EDGE Analysis

The Angels have good starting pitching depth, leaving Hector Santiago, Tyler Skaggs, Matt Shoemaker, and Nick Tropeano to battle for the final spot. Injuries could open up additional spots, but Heaney has seemingly pitched well enough to secure his place behind Garrett Richards, Jered Weaver, and C.J. Wilson as the arms inked into starting slots in April. In 135 career big league innings, Heaney has posted a modest 6.5 K/9, but he's shown control in line with his minor league numbers (2.3 BB/9). He handles left-handed hitters with relative ease, but Heaney needs to find a way to generate more whiffs against right-handers going forward (15.4% K% in 2015).

Heaney (6-4) closed out his regular season with a dud Thursday, walking a season-high five and allowing five hits and four runs in 4.1 innings against Texas.

EDGE Analysis

Frankly, Heaney was fortunate to navigate his way out of a far uglier final line. All in all, this was a solid season for the young lefty, who wraps things up with a decent 3.49 ERA and 1.20 WHIP in 18 starts for the Angels. However, it's not as pretty when you break it down -- in his first 10 starts, Heaney won five games and delivered a 2.43 ERA with a 44:10 K:BB in 63 innings, but in the final eight, he won just once while putting up a 5.06 ERA and 34:18 K:BB in 42.2 innings. Still, the Angels are just a game out of a wild-cast spot, and if they earn their way into postseason play, Heaney's a likely candidate to pick up a start.

Heaney hurled a quality start on Saturday, striking out five batters across six innings while allowing two runs on five hits and two walks in a no-decision against Seattle.

EDGE Analysis

Heaney was actually lucky not to allow five runs, as a three-run homer by Jesus Montero was robbed by Mike Trout for one of the catches of the season. In any case, he pitched well for the third straight start and it appears more and more that the Angels got a steal when they traded for Heaney at the beginning of the season. Th lefty now has a 3.29 ERA and 1.15 WHIP in 17 starts this season.

Heaney is slated to start Game 1 of Saturday's doubleheader with the Twins.

EDGE Analysis

With Friday's game rained out, Heaney will simply move back to start Game 1 of Saturday's twin bill. However, he's now set to oppose Kyle Gibson instead of Mike Pelfrey, as Minnesota decided to flip-flop its starters.

Heaney will not make his scheduled start Friday against Minnesota, as the game was postponed due to rain.

EDGE Analysis

The Angels and Twins will play a doubleheader Saturday to make up for the rainout, and Heaney figures to simply move back to start one of the two games.
