J.A. Happ allowed four runs over six innings on Wednesday in a win over the Royals.
Happ improves to 3-1 on the season. While he did give up the four runs, he was able to strike out eight while also getting the victory, so we'll call it a mixed fantasy day for the southpaw. He'll be back on the mound next week against the Red Sox on Tuesday. Apr 18 - 7:19 PM

J.A. Happ pitched six innings of one-run ball and struck out nine in a win over the Orioles on Monday.

Happ improved to 2-1 with a 3.94 ERA and 23 strikeouts through 16 innings. He gets the slumping Indians next time out, which doesn't seem like such a bad matchup for a lefty right now. He'll be worth having active in mixed leagues most weeks.
Apr 9 - 11:37 PM

J.A. Happ allowed three runs -- two earned -- over 4 2/3 innings Thursday in an Opening Day loss to the Yankees.

Happ struck out five, issued just one walk, and yielded only four hits -- but one of those hits was a monster two-run homer by Giancarlo Stanton in the top of the first inning. Happ stands 0-1 with a 3.86 ERA through one start. He should have an easier time against the White Sox next time out.
Mar 29 - 7:09 PM

J.A. Happ pitched four scoreless innings Friday in his start against the Rays.

With Marcus Stroman's shoulder pushing him back, Happ will get the Opening Day assignment for the Jays this year. He has a 3.05 ERA in 20 2/3 innings this spring.
Mar 23 - 4:59 PM

J.A. Happ has been officially named the Blue Jays' Opening Day starter.

The situation had been trending in this direction for a couple weeks with Marcus Stroman slowed in camp by a shoulder injury. It's the first career Opening Day nod for Happ, who owns a strong 3.33 ERA, 1.23 WHIP, and 8.1 K/9 in 340 1/3 innings over the last two seasons. The 35-year-old left-hander should again be a useful mid-to-late round fantasy starter.
Mar 20 - 10:14 AM

J.A. Happ threw six innings of one-run ball Sunday in a Grapefruit League start against the Pirates.

The only real blemish was a Starling Marte solo home run in the top of the sixth inning. Happ struck out five and now holds a 3.78 ERA with 15 strikeouts through 16 2/3 innings this spring. The veteran left-hander is expected to serve as the Blue Jays' Opening Day starter.
Mar 18 - 2:52 PM

According to Jon Morosi of, the Blue Jays are leaning toward J.A. Happ as their Opening Day starter against the Yankees.

Happ is both the oldest and most experienced starter in the Blue Jays' starting rotation. He has never pitched on Opening Day for any of the five clubs that have employed him, but with Marcus Stroman battling shoulder inflammation and Aaron Sanchez coming off a lost 2017, the choice this year for Jays manager John Gibbons is actually pretty obvious. Happ, 35, holds a 3.33 ERA, 1.23 WHIP, and 8.1 K/9 in 340 1/3 innings over the last two seasons.
Mar 14 - 8:39 AM

J.A. Happ yielded one run in three innings Wednesday in a win over the Pirates.

Happ has allowed two runs and struck out six in six innings. He could be the Jays' Opening Day starter with Marcus Stroman set back by injury.
Mar 7 - 4:34 PM

J.A. Happ tossed a scoreless inning Sunday in his Grapefruit League debut against the Tigers.

Happ surrendered a one-out double to Niko Goodrum in the top of the first inning, but he struck out JaCoby Jones and John Hicks to escape the frame unscathed. The veteran right-hander should again be a solid mid-to-low tier fantasy starter in 2018. He posted a 3.53 ERA and 142 strikeouts over 145 1/3 innings last season.
Feb 25 - 3:30 PM

J.A. Happ limited the Red Sox to one run in seven innings and struck out nine in a victory Tuesday.

Happ isn't expected to start again this weekend, so he ends the year 10-11 with a 3.53 ERA in 25 starts. By some measures, he's pitched as well this year as in his 20-4 campaign in 2016. His ERA isn't quite as good (he had a 3.18 mark last year), but his FIP is slightly better this season and his strikeout rate (142 K in 145 1/3 IP) is considerably higher.

J.A. Happ allowed a lone run over 6 2/3 innings Thursday but took the loss against the Royals.

Happ held the Royals to a run on seven hits, but the hapless Jays hitters could muster just two hits in the losing effort. The southpaw struck out six while walking two in the outing. The loss snapped a three-start winning streak and dropped him to 9-11 in 24 starts overall. Happ will carry a 3.64 ERA, 1.35 WHIP and 133/46 K/BB ratio into a meeting Tuesday with the Red Sox.

J.A. Happ allowed two runs in six innings of work in a victory over the Tigers on Sunday.

Only one of the runs was earned, and Happ allowed just five hits and two walks while striking out nine. It lowers the left-hander's ERA to 3.73, and it's his eighth win of the season. He'll go up against the Twins and mighty Bartolo Colon on Friday.
Sun, Sep 10, 2017 04:20:00 PM

J.A. Happ allowed three runs -- one earned -- over 5 2/3 innings Monday in a win over the Red Sox.

Happ committed a throwing error in the bottom of the second inning that led to Boston's first two scores. The one earned run against him came on an RBI single by Eduardo Nunez in the bottom of the sixth. Happ allowed six total hits in the game, along with three walks. He struck out three. The veteran left-hander will bring a 7-10 record, 3.85 ERA, and 1.37 WHIP into his next start at home against the Tigers.

J.A. Happ held the Red Sox to one run over six innings in a no-decision Wednesday.

Happ walked four tonight, but the only damage came on Hanley Ramirez's solo homer inm the fifth. It was the first time this season that he ended up with more walks than strikeouts (just two tonight). He had fanned 38 in his previous five starts this month.

Jon Heyman of FanRag Sports reports that J.A. Happ was pulled back on waivers after being claimed.
