J.A. Happ allowed four runs in two innings against the Orioles on Thursday.

Neither Happ nor Orioles starter Chris Tillman were long for this game, as the contest was delayed for a long stretch during the third inning. Rain or no, Happ started out terribly enough, allowing a two-out grand slam to Steve Pearce in the first inning. He struck out three and walked two in his short time on the mound. While his 3.61 ERA and 1.20 WHIP are fine, as is his 37/11 K/BB ratio over 47 1/3 innings, owners should be cautioned that the last time Happ posted an ERA under 4.22 was in 2010. In his continued quest to defy his own history, Happ will take to the road for a start against the Rays in his next outing.
May 21 - 6:23 PM

J.A. Happ pitched seven innings of one-run ball Friday against the Red Sox.

Happ struck out just three and got 11 flyball outs, versus six on the ground. It's not exactly how one would draw it up, but it worked for him tonight, and he brought his ERA down to 2.98. He'll face the Orioles in Baltimore next time out, so if he gives up as many flyballs again, odds are that one or two will leave the yard.
May 16 - 12:54 AM

J.A. Happ held the A's to one run over five innings in a victory Saturday.

Happ struck out eight in his third win of the year. He's allowed two runs or fewer in five of his six starts, giving him a nifty 3.29 ERA. Next up for him is a more difficult assignment against the Red Sox.
May 10 - 1:29 AM

J.A. Happ was largely ineffective against the Astros on Sunday, as he allowed six runs over six innings.

While Happ did manage six strikeouts (he now has 15 strikeouts over his last 12 2/3 innings), he also served up two home runs. Evan Gattis smashed a three-run shot in the first inning and Chris Carter hit a two-run shot in the third. Marwin Gonzalez singled in the sixth run an inning later. Prior to Sunday, Happ had not allowed more than two runs in a single start, so even with the six runs tacked to his line, his ERA still stands at a respectable 3.51. He holds a 24/6 K/BB in 23 1/3 innings and will take to the road against the Rangers in his next start.
May 3 - 5:08 PM

J.A. Happ struck out nine while allowing one run over 6 2/3 innings in Tuesday's 2-1 win over the Rangers.

Happ was an equal opportunity strikeout artist, punching out seven of the Rangers' nine batters at least once in the game. He spread six hits and a walk over his 6 2/3 innings, lowering his ERA to 2.30 with a 1.06 WHIP. Happ will try to run his record to 3-1 when he takes on the Astros Sunday in Houston.
Apr 28 - 10:58 PM

J.A. Happ held the Astros to two runs over 7 1/3 innings in Wednesday's victory.

Happ scattered eight hits and struck out five without issuing a walk. He was blanking the Astros through the first four innings, but a fifth inning RBI single by Jose Altuve and a seventh inning solo home run by Chris Carter dented his line with a few runs. Happ, who hasn't put up an ERA of lower than 4.22 since 2010, currently holds a 2.61 mark. We'll go out on a limb and predict that that's going to rise. He'll take his career-defying numbers on the road against the Rangers in his next outing.
Apr 23 - 12:50 AM

J.A. Happ yielded two runs in seven innings Friday in a loss to the Rangers.

Happ has given the Mariners consecutive quality starts with no victories to show for it. His next start will come against the Astros, giving him a chance to rack up more strikeouts than the four he's totaled in his first two starts.
Apr 18 - 1:21 AM

J.A. Happ held the A's to two run over 6 1/3 innings Saturday in the Mariners' extra-innings victory.

Happ was efficient and effective, needing only 82 pitches to get through his six-plus frames. He walked none and struck out one. The 32-year-old left-hander gets the Rangers at home next week. He's only a fringe option in AL-only fantasy leagues.
Apr 11 - 7:51 PM

J.A. Happ pitched well in his final Cactus League start on Friday, firing four shutout innings in a victory over the Rockies.

Happ scattered just two hits and walked a pair while whiffing four on the evening. While he owns an unsightly 6.11 ERA on the spring, he is still assured of a rotation spot to begin the season and could have some fringe value in AL-only formats.
Apr 4 - 1:25 AM

J.A. Happ was once again obliterated in a losing effort against the Padres on Sunday, surrendering six runs (five earned) on 11 hits over his five innings.

Happ issued a pair of walks and struck out three on the afternoon. He now owns a troublesome 7.90 ERA and 1.98 WHIP in 13 2/3 spring innings. The Mariners brass has to be considering if they'd be better off with Roenis Elias in the rotation instead of Happ at this point.
Mar 29 - 9:59 PM

J.A. Happ was hit hard in Tuesday's loss to the Padres, surrendering six runs (five earned) on eight hits over 3 2/3 innings.

Happ also issued three free passes while striking out three. The Padres struck for three runs each in the second and third frames, with Justin Upton belting a two-run homer along the way. While he's locked into a spot in the Opening Day rotation, Happ has posted a disappointing 7.27 ERA over 8 2/3 innings in Cactus League action.
Mar 24 - 9:52 PM

J.A. Happ delivered a strong start in Friday's Cactus League victory over the Brewers, allowing just one hit over three scoreless innings.

The veteran southpaw struck out a pair on the afternoon. He's locked into a spot in the Mariners rotation to begin the season, though with a career 4.24 ERA and 1.39 WHIP, not even the friendly confines of Safeco Field will make him mixed league relevant.
Mar 13 - 7:59 PM

J.A. Happ yielded a pair of runs in his two innings of work in Sunday's 10-1 loss to the Reds.

Both runs came in the bottom of the second on Donald Lutz's two-run home run. Happ overall gave up two hits and a walk while striking out one. The lefty, acquired from the Blue Jays in the winter, appears to have the Mariners' fourth rotation spot cemented.
Mar 8 - 6:34 PM

Mariners pitching coach Rick Waits said Saturday that J.A. Happ has been working on his changeup and plans to use the pitch with a much higher frequency in 2015.

The changeup was arguably the veteran southpaw's worst pitch last season, which could be why he only used it 9.5% of the time, down from his career usage of 12.3%. If Waits and company can improve the pitch though, and provide more deception and separation from his fastball, it could become more of a weapon for him.
