Magnante will be entering his fourth season with the Ports and 22nd with the Athletics' organization. In 2017, the Ports finished with a 71-69 overall record, winning the division in the second half and making an appearance in the post-season.

Prior to Stockton, Magnante served as the manager of Class-A Beloit in 2014 after spending eight seasons with the A's short-season teams in Vermont (2011-2013) and Vancouver (2006-2010). Magnante acted as a scout with the Athletics prior to his coaching career, from 1995-2005, and has been credited with signing both Barry Zito and Bobby Crosby to the A's organization.

Magnante served as the manager of the South African National Team during the 2006 and 2009 World Baseball Classics and managed the team during the 2013 qualifying tournament. The University of California, Santa Barbara alumnus was drafted in the 13th round of the 1969 draft by the Cleveland Indians and spent one year in the minor leagues with their Class-A affiliate.

Bryan Corey, a California native, joins the Ports after spending 2017 with short-season Vermont. Prior to that, Corey served as a Major League advance scout for Milwaukee (2015-2016) and a Four Corners scout for Cleveland (2013-2104).

Originally drafted as a shortstop by Detroit in the 1993 draft, Corey was converted to a pitcher after two pro seasons. He spent the next 18 seasons on the mound, five of those being in the majors with Arizona, Los Angeles, Texas, and San Diego. He was also part of the team that brought a World Series Championship to Boston in 2007.

Brian McArn won't be far from where he makes his off-season home in Elk Grove, Calif. He'll be returning to the Ports following a stint with Midland, and 2018 will be McArn's 21st overall season as a hitting coach in the Athletics' system.

Prior to joining the A's organization, McArn served as the hitting coach for the Single-A Vermont Expos in the New York-Penn League and was an assistant coach at American River Junior College in Sacramento.
