Mathisen went 2-for-4 with a solo home run and a two-run shot in Wednesday's 7-3 win over the Rangers.
After opening his MLB career in a 2-for-19 rut, Mathisen found the bleachers twice on Wednesday. He will look to improve on his .182/.280/.455 slash line over the season's final games.
Mathisen went 1-for-4 with two RBI in Saturday's 7-3 loss to Seattle.
Mathisen started at third base for the third time in the last four games, all against left-handed starters. Eduardo Escobar shifted to designated hitter Saturday but has also played second base during Mathisen's stretch of playing time. With second baseman Ketel Marte (wrist) sidelined and no defined DH, manager Torey Lovullo can move pieces in and out pending the handedness of the opponent's starter.
Mathisen started at third base and went 0-for-4 in Monday's 4-2 loss to the Giants.
Mathisen was called up Monday, but at age 26, he's not considered a prospect. He replaced a resting Eduardo Escobar but will play a backup infield role going forward.
Mathisen was recalled by the Diamondbacks on Sunday.
Mathisen provides depth across the infield as he played at first, second and third base at Triple-A Reno during the 2019 season. He also managed a 1.004 OPS in 87 games in the friendly hitting environment.
Mathisen will be part of the Diamondbacks' taxi squad, Nick Piecoro of the Arizona Republic reports.
The three-man taxi squad is made up of players not on the active roster that will accompany teams on road trips, providing immediate replacements for an injured or COVID-19 infected player. Mathisen can fill in at all three infield base positions. The 26-year-old hit .283 with 23 homers and a 1.004 OPS in 87 games with Triple-A Reno last season.
Mathisen was optioned to Triple-A Reno on Monday.
Mathisen's contract was selected in November to protect him from the Rule 5 draft, but it was unlikely that he'd be able to make the major-league squad to begin the season despite working in major-league camp. The 26-year-old has been effective this spring, hitting .429/.500/.786 with one home run and five RBI over 14 at-bats in the Cactus League.
Mathisen's contract was selected by the Diamondbacks on Wednesday.
The move protects Mathisen from the Rule 5 draft. The 25-year-old doesn't come with a ton of prospect pedigree, but he managed a strong .283/.403/.601 slash line in 87 games for Triple-A Reno last season.
