With two swingmen stepping into the rotation, the Seattle Mariners bolstered their bullpen prior to Sunday’s game by recalling right-hander Mayckol Guaipe from Triple-A Tacoma.
The move came after the Mariners cleared space by optioning lefty starter Mike Montgomery to the Rainiers.
“Obvious reasons,” manager Lloyd McClendon said. “We needed another right-hander ... it just made sense to bring back Guaipe.”
The Mariners needed another bullpen arm as they started Edgar Olmos in Sunday’s series finale against the White Sox and Vidal Nuno will start in Monday’s series opener at Houston.

Guaipe, 25, returns for a fourth time this season and saw immediate action. He coughed up a one-run lead Sunday in the seventh inning but was positioned for a victory when the Mariners scored in the eighth.
That slipped away when the White Sox scored an unearned run with two outs in the ninth inning before gaining a walk-off victory in the 11th inning.
While Guaipe had a 2.87 ERA in 38 games at Tacoma, he now sports a 7.07 ERA in nine big-league appearances.
Montgomery surrendered his spot in the rotation Sunday to Olmos after compiling an 8.33 ERA over his previous nine starts. He was 4-6 with a 4.60 ERA overall in 16 starts following his June 2 recall from Tacoma.
Plans call for Montgomery to make two starts for the Rainiers, and his recall to the big leagues will hinge on his performance. Tacoma’s season ends on Sept. 7.
“It’s command of the zone,” McClendon said. “His stuff is plenty good enough, but there’s no defense for walks. You just can’t do it.”
Rookie shortstop Ketel Marte could return to the lineup as soon as Monday after showing notable overnight improvement in a strained right hamstring that forced him to leave Saturday’s game in the eighth inning.
“He’s day to day,” McClendon said, “but he feels much better today. Strength-wise, he’s four out of five on the scale. He’s going to test it (Monday), and if he can go, he’ll go (Monday). We’ll see.”
Marte, 21, started the previous 14 games at shortstop and is batting .289 with a .355 on-base percentage in 26 games since his July 31 recall from Tacoma.
LONG 9 INNINGS
The Mariners’ 7-6 victory over the White Sox on Saturday took 4 hours, 16 minutes, which tied for the longest nine-inning game this season in the majors.
Detroit’s 9-6 victory at Cleveland on April 11 also required 4:16.
Sunday’s series finale wasn’t much better. It lasted 4:01, although it went 11 innings.
The Mariners have played six nine-inning games that required four hours or more since 1987, when Major League Baseball officially began tracking the time of games.
Saturday’s victory was their second-longest during that span, exceeded only by the 4:20 required for a 14-13 loss to Baltimore on May 17, 1996.
The Orioles scored four runs in the ninth against Norm Charlton for a walk-off victory.
Single-A Everett right fielder Alex Jackson, the organization’s top prospect, had the first multi-homer game of his career Saturday in a 9-3 loss to Tri-City (Padres).
Jackson, 19, is putting on a strong closing kick to a roller-coaster first full pro season by batting .303 (10-for-33) with a .429 on-base percentage, three doubles and four homers in his past 11 games.
The Mariners selected Jackson with the sixth overall pick in the 2014 draft. Overall, he has a .257 batting average/.357 on base-percentage/.514 slugging percentage slash in 42 games at Everett after his demotion from Single-A Clinton.
It was 25 years ago Monday — Aug. 31, 1990 — that Ken Griffey Sr. and Ken Griffey Jr. played together for the first time in a major league game.
Griffey Sr. played left field and batted second, while Griffey Jr. played center field and batted third. Both had singles in the first inning against Storm Davis in a 5-2 victory over Kansas City at the Kingdome.
The Mariners struck out a season-high 19 times in Sunday’s game, which matched an all-time record for a White Sox opponent.

The Mariners open a three-game series at first-place Houston at 5:10 p.m. (PDT) Monday at Minute Maid Park.
With Felix Hernandez getting bypassed on this cycle through the rotation, left-hander Nuno (0-1, 3.21 ERA) will face Astros ace Dallas Keuchel (15-6, 2.28).
