Ferguson was optioned to Triple-A Las Vegas on Friday.

Ferguson appeared in nine games with the Athletics, tallying a 4.50 ERA over 10 innings. However, he'll be pushed back to the Triple-A level, while Dany Jimenez and Brady Basso join the big-league roster.

The Athletics announced Friday that Erceg (forearm) was placed on the 15-day injured list retroactive to May 26.

Erceg hasn't pitched since May 25 due to forearm tightness and will officially be sidelined until at least June 10. Prior to the injury, Erceg had operated as Mason Miller's setup man, a role that Austin Adams or Scott Alexander could fill until Erceg returns.

Jimenez was recalled from Triple-A Las Vegas by Oakland on Friday.

Jimenez will rejoin the Athletics just a month after being sent down to the team's Triple-A affiliate. The 30-year-old righty has appeared in 15 games with Oakland this year, recording a 3.68 ERA and 1.50 WHIP across 14.2 innings.

Lynch was optioned to Triple-A Omaha after Thursday's 7-6 loss to the Twins.

The southpaw was brought up to the majors as a spot starter for Brady Singer (illness) and yielded two earned runs and a pair of homers across five innings Thursday against the Twins. Lynch has been reliable in his 12 big-league innings this season with just those two earned runs allowed, but he'll likely remain at the Triple-A level while the Royals' rotation is at or near full health.

Kansas City recalled Klein from Triple-A Omaha on Friday.

The 24-year-old righty will rejoin the Royals after being optioned down in late April, while southpaw Daniel Lynch gets sent down to Omaha in a corresponding move. Klein has seen just one inning with Kansas City this year and logged two strikeouts with no runs allowed.

The Rays selected Sterner's contract from Triple-A Durham on Friday.

The right-hander has a 3.60 ERA, 1.04 WHIP and 33:8 K:BB over 25 innings for Durham this year to earn his first taste of the big leagues. Sterner should fill a low-leverage bullpen role for the Rays.

Ferguson (0-1) was charged with the loss against the Rays in extra innings Thursday, allowing an unearned run across 1.1 hitless innings. He struck out one.

Ferguson entered the game in the 11th with the score knotted at 5-5 and retired the side in order before returning for the 12th and inducing an inning-opening groundout that moved phantom runner Jose Caballero to third base. T.J. McFarland subsequently allowed Caballero to cross the plate on Richie Palacios' walk-off single, saddling Ferguson with the loss. The right-hander did at least bounce back from a rocky outing Wednesday, one that had seen him allow a run on three hits over two-thirds of an inning. Ferguson is likely to continue seeing work primarily in lower-leverage scenarios, and he holds a 4.50 ERA and 1.40 WHIP over his nine appearances this season.

Stratton (2-3) took the loss and a blown save Thursday versus the Twins, allowing four runs on three hits and two walks while striking out two over two-thirds of an inning.

Stratton worked the sixth inning, relieving starter Daniel Lynch while the Royals were ahead 4-3. That lead didn't hold, as Stratton gave up an RBI single to Max Kepler and a three-run triple to Carlos Correa before John Schreiber finished off the frame. While Stratton has kept runs off the board in seven of his 10 appearances in May, he's allowed seven runs with an 11:6 K:BB over 11 innings for the month. He's at a poor 6.00 ERA, 1.38 WHIP and 22:16 K:BB with three saves, three holds and two blown saves over 24 innings this season, serving as an occasional high-leverage option.

Lynch allowed three runs (two earned) on five hits and struck out two without walking a batter in a no-decision Thursday versus the Twins.

Lynch got the nod for a spot start when Brady Singer (illness) was deemed unavailable to pitch Thursday. The three runs on Lynch's line came on a pair of home runs by Ryan Jeffers, though the Kansas City southpaw still left the game with a lead before Chris Stratton squandered it in the sixth inning. Lynch has a 1.50 ERA, 0.75 WHIP and 8:2 K:BB over 12 innings across three outings (two starts) at the major-league level. Assuming Singer can rejoin the rotation for his next start, Lynch may either be moved to the bullpen or sent back to Triple-A Omaha for a fresher arm.

Miller was charged with a blown save in Thursday's 6-5 loss to Tampa Bay in 12 innings, allowing two runs (one earned) on one hit and three walks over two innings. He struck out four.

Jose Siri's game-tying homer in the bottom of the ninth was the first given up by Miller this year while also resulting in his first blown save in 12 chances. Despite Thursday's hiccup, it's been an excellent start to the season for the 26-year-old Miller -- his ERA now sits at 2.08 with a 0.88 WHIP and 51 strikeouts, the most among qualified relief pitchers, through 26 innings.
