Ronald Guzmán of the Giants recently underwent an MRI after experiencing some forearm discomfort. The team provided an update to reporters today, with Susan Slusser of the San Francisco Chronicle among those to relay the information. Guzmán has a left pronator strain but will not require surgery. Slusser later got an update from Guzmán himself, who said that he won’t throw for the next four weeks and will likely miss six-to-eight weeks in total.

Guzmán, 28, has spent most of his career as a first baseman but is attempting to become a two-way player this year. He signed a minor league deal with the Giants this offseason, explaining in March that they were the only team that would let him try his hand at pitching.
