Mike Calabrese recommended backing the Oakland Athletics as an underdog against the New York Mets, pointing to pitcher JP Sears' recent form with back-to-back quality starts as a key factor. Calabrese mentioned that Sears is trending upward, while the Mets lineup continues to disappoint. He sees current matchups as favorable for the Athletics due to Sears' consistent performances and the Mets' continued offensive struggles. This combination makes Oakland a compelling and high-value underdog pick.
