Here are some tidbits in high school baseball this week you should know:

1. BC High storms to top of Catholic Conference – The Eagles have jumped to the head of the Catholic Conference just four games into the season, going undefeated in that span. Norm Walsh was confident about his team’s pitching staff heading into this year and the team has shown why. BC High started the year outscoring Lowell and Brockton by a combined 19-14 before a 2-1 victory over conference rival Malden Catholic. They went on to crush Cheverus (Maine) 12-3. Xaverian is right behind the Eagles at 3-2, but a strong start nonetheless by our neighbors in Boston.

2. Xaverian turns early stumble around – Last week looking at Xaverian, the Hawks had just begun the season 1-2. It was an early stumble after Xaverian had won the Division 1 crown last year. Things quickly turned around with two straight wins against Lincoln-Sudbury and Norwood. The Hawks surrendered just six runs over those two contests as they moved a game over .500.

3. Early battle for first in Catholic Central – Archbishop Williams and Arlington Catholic have both started the season at 4-0 with St. Mary’s at 3-2 in third place. The Bishops and Cougars have both been lighting up scoreboards to start the year. St. Mary’s has suffered two losses but have outscored opponents 26-7 in its three victories. Considering the offense on all three teams, it could be a season full of high-scoring games in the league.

4. Lincoln-Sudbury falling – All Dual County League members have won at least one game this year, but Lincoln-Sudbury can’t say it has won anymore than that. The Warriors have lost to some tough opponents like Xaverian and Nashoba, but a loss is a loss and at No. 19 in the Globe preseason top 20 baseball poll, Lincoln-Sudbury needs to start putting some wins together to stay on the list.

5. Frank Carey reaches 700 wins – If you checked the high school sports blog last night, you probably already heard the news but this milestone is worth mentioning again. North Reading coach Frank Carey recorded win number 700 in a 9-1 victory over Newburyport Monday night. Carey has coached the Hornets for 46 seasons and opened the seasons with 697 wins on his resume. The Hornets have gone 3-0 to start the season and made sure to get their coach to his milestone as fast as possible.
