For the third time this season, the San Francisco Giants have made a trade with the Seattle Mariners for a Triple-A infielder, but this time it took a prospect and not cash to get something back.

The Giants traded for Donovan Walton, who has experience playing shortstop, second, third, and left field.  Walton, on the year, is batting .294/.368/.510 over 12 games in Triple-A Tacoma, with four doubles, two triples, and a home run.  In 2021, he hit .304/.395/.519 in Triple-A.

Walton has played parts of four seasons in the Majors, including in 2022 with one game in which he has no at-bats but scored a run.  In 2021, he hit .206/.254/.365 across 24 games with Seattle, with two doubles, a triple, and two home runs.  Walton was originally drafted in the 5th round of the 2016 draft by the Mariners.

In exchange, the Giants sent right-handed starting pitcher Prelander Berroa, who has a 0.68 ERA in four games at High-A this season, with 15 strikeouts to six walks in 13.1 innings.  In 2021, Berroa had a 3.56 ERA in Low-A San Jose, with 135 strikeouts to 53 walks in 98.2 innings.  The Giants originally acquired Berroa in the July 2019 trade with the Minnesota Twins for Sam Dyson alongside pitcher Kai-Wei Teng and outfielder Jaylin Davis.  The Giants designated Davis for assignment last week and he was claimed by the Boston Red Sox.

The trade is the Giants third with the Mariners over the last few weeks for Triple-A infielders.  The previous two, 3B Kevin Padlo and 1B Mike Ford, were both traded for cash after the Mariners had designated them for assignments.  In the past two weeks, the Giants have also traded for Marlins Triple-A shortstop Isan Diaz.
