SEATTLE -- With Triple-A Tacoma's season coming to a close Monday night, the Mariners added a trio of September reinforcements to their big league roster Tuesday.
"Most of these guys have been here at some point during the season with us, so you kind of already know the personality," said manager Scott Servais. "The guys coming up, they understand where we're at in the season, we're still fighting for our playoff lives, and just willing to help any way they can."
First baseman Daniel Vogelbach, right-handed pitcher Casey Lawrence and utility man James Beckham were all recalled from Triple-A. The Mariners now carry 35 active players out of the September maximum of 40.
This marks the fifth big league stint of 2018 for Vogelbach, who hit .290/.434/.545 with 20 home runs for the Rainiers this season, leading the Pacific Coast League in on-base percentage while ranking third in OPS, sixth in slugging and second in walks. In 79 plate appearances with the MLB club, the 25-year-old put up a line of .212/.342/.333 with a pair of homers.
Vogelbach is unlikely to play in the next few games due to a hamstring injury, Servais said. He sustained the injury running through a stop sign in a turn around third base and last played Aug. 24.
Lawrence, 30, has already seen time with the Mariners four times this season, making eight appearances primarily in long relief and low-leverage situations and pitching to an 8.31 ERA over 17 1/3 innings. He made 16 starts and three relief appearances in Triple-A, totaling a 3.31 ERA with 8.2 strikeouts/nine innings and 1.2 walks/nine innings.
Beckham will make his fourth stint with the Mariners after hitting .302 with a .400 on-base percentage in 94 games with Tacoma. He got time at all four infield positions plus left field this season in Triple-A. The 31-year-old collected eight hits and three walks over 41 MLB plate appearances in 2018.
Cruz nominated for Clemente Award

All 30 Major League clubs announced their nominees for the Roberto Clemente Award on Tuesday, and designated hitter Nelson Cruz earned the Mariners' nod.
Cruz launched his Boomstick23 Foundation in 2016. In 2018, Cruz held a Spring Training event for the Boomstick23 Foundation and Amyloidosis Support Groups, raising $22,000 and continued awareness for the two charities.

The Roberto Clemente Award is the annual recognition of a player who best represents the game of baseball through extraordinary character, community involvement, philanthropy and positive contributions, both on and off the field.
Diaz gets more hardware
Edwin Diaz has been named American League Reliever of the Month, again.
This is the fourth such honor for the Mariners closer in 2018 and his third consecutive month winning the award. Diaz posted a 1.64 ERA while converting 10 of 11 save opportunities and striking out 51.2 percent of batters faced in August.
Servais spoke to whether Diaz should garner Cy Young support for his 2018 campaign.
"If there's any [reliever] that certainly should be in the discussion, it is Eddie," Servais said. "I would hope he gets a few votes. I think he will. Certainly in my mind, there's been no more valuable pitcher from where I sit every night. That's the guy we're looking to get the ball to and he's been as consistent as they come."
Díaz is the first player to win four monthly awards in a single season since Michael Trout won four AL Rookie of the Month awards in 2012 and the first non-rookie since Pedro Martínez earned four AL Pitcher of the Month honors in 1999.
Diaz has converted 52 saves on the season, good for a tie for eighth-most in a single season. With another save, he'll slip into a four-way tie for fifth.
